PTC resettable fuses, often called polymeric positive temperature coefficient (PPTCs) or thermally sensitive polymer fuses, are a kind of electrical component that are used to limit the current in an application by opening and resetting in an electrical circuit. SMD2920P300TSA/15 is one of the popular PTC resettable fuses. It has a rated current of 300mA and housing size of 2.1 x 3 mm, which is suitable for a wide variety of applications.

The working principle of the SMD2920P300TSA/15 PTC resettable fuses is quite simple. It has two layers of temperature sensitive resistors that are connected in series. When a certain amount of electric current passes through the two resistors, it will generate heat and increase the temperature of the resistor. The increased temperature will cause the resistors to become more resistance in nature, eventually leading to the PTC resettable fuse breaking the circuit.

The application field of the SMD2920P300TSA/15 PTC resettable fuses is wide. It is used in a variety of consumer and industrial applications. In consumer electronics, SMD2920P300TSA/15 fuses can be used in the power loop of smartphones, tablets, digital cameras, and other electronic devices, where the current is used to protect the device from electrical over-heating or short circuit. In medical devices, SMD2920P300TSA/15 fuses can be used to protect the device from overheating and short circuits.
